Juniperus 'pygmaea' from Azerbaijan was analyzed by DNA sequence data from nrDNA plus four cp DNA regions (4315 bp) and found in a clade with J. communis 'oblonga' (= J. communis) Armenia, not with J. c. forma pygmaea of Bulgaria. It seems prudent to not recognize this variant taxonomically but treat it as J. communis.
